Added new event types for authorization success and failure in audit_events.py. - Extended TokenRequest and TokenResponse models to include role for RBAC. - Modified create_access_token function to accept role parameter. - Updated obtain_token endpoint to handle role assignment. - Integrated RBAC checks in contacts, telemetry, and weather routers using require_permission. - Created rbac.py for RBAC logic and role-permission mapping. - Defined roles and permissions in rbac_roles.py. - Added comprehensive tests for RBAC functionality, including integration tests for endpoint access based on roles. - Documented RBAC implementation and usage in AUTHORIZATION.md. --- README.md | 19 +- docs/AUTHORIZATION.md | 192 ++++++++++++++ skylink/audit.py | 56 +++++ skylink/audit_events.py | 10 + skylink/auth.py | 12 +- skylink/rbac.py | 199 +++++++++++++++ skylink/rbac_roles.py | 137 ++++++++++ skylink/routers/auth.py | 6 +- skylink/routers/contacts.py | 5 +- skylink/routers/telemetry.py | 5 +- skylink/routers/weather.py | 5 +- tests/security/conftest.py | 17 +- tests/test_gateway_contacts_routing.py | 7 +- tests/test_rbac.py | 225 +++++++++++++++++ tests/test_rbac_integration.py | 331 +++++++++++++++++++++++++ 15 files changed, 1202 insertions(+), 24 deletions(-) create mode 100644 docs/AUTHORIZATION.md create mode 100644 skylink/rbac.py create mode 100644 skylink/rbac_roles.py create mode 100644 tests/test_rbac.py create mode 100644 tests/test_rbac_integration.py diff --git a/README.md b/README.md index c70187c..60c67e0 100644 --- a/README.md +++ b/README.md @@ -33,7 +33,7 @@ This project is a **reference implementation** designed to teach and demonstrate -
